In the footage, which was shot on the mobile phone of concert-goer Diarmund Nagle, two mysterious bright, white lights are seen shooting across the sky just to the right side of the stage just as the band launch into the chorus.

The lights hover in the sky for a very brief moment before they suddenly disappear into thin air, just as quickly as they came.

Other festival attendees are seen holding their arms towards the sky as they dance and sing to the band's music - with most of them seeming to be unaware of the 'blink-and-you'll-miss-it' UFO light show .

And even Diarmund was oblivious to the mysterious objects at the time, having simply pulled his phone out to record the band singing their famous hit.

It has been three years since their last Hyde Park gig, when Blur performed at the Barclaycard Presents British Summertime concert to coincide with the end of the Olympics.

Their latest Hyde Park appearance also marked their first London festival since the release of their latest album The Magic Whip in April - their first record as a four-piece in 12 years.

The band opened with Go Out - lead single off the new record - before frontman Damon Albarn distributed ice creams to members of the crowd on the front row from a van parked on stage after the second song, There's No Other Way.

Earlier this week mysterious footage from NASA's live feed appeared to show three blurry UFOs leaving the Earth's atmosphere and flying into space.

But as claims emerged that NASA had then abruptly cut off the footage, conspiracy theorists were convinced the clip was more proof of alien visitors.
